  • Pellets were prepared according to Samples S19 and S20 and were placed in an oven based vaporiser (Vicod 5G, http://www.atmosrx.comA icod-5G. html) to assess the ability of each product to generate an aerosol. Three repetitions were carried out for each sample. Two tests were run whereby for the first test, pellets were inserted into the device with the oven already at 200°C (results of Table 3), and for the second test, pellets were inserted into the device and then the oven was heated to 200°C. Airflow was drawn through the device whilst it was turned on and any resulting aerosol captured on a Cambridge Filter Pad (CFP). The CFP (and holder) was weighed before and after the test to check the mass change which is indicative of aerosol formation from the aerosolisable product.
